Abstract
The invention discloses a sheet molding compound (SMC) optical cable fiber distributing box which comprises a box body. Arc wire-wrap boards are arranged in the box body in pairs. The arc wire-wrap boards comprise sleeves and plug sticks. The plug sticks are inserted into the sleeves in an arranged mode. Sliding grooves are arranged in the box body and the arc wire-wrap boards are arranged in the sliding grooves in a sliding mode. Fixed grooves matched with the plug sticks are arranged behind the sliding grooves in the box body. The plug sticks enter into the fixed grooves through the sleeves. The sheet molding compound optical cable fiber distributing box can ensure that a cable coil can be tightly wound on a coil disc so that a too small bent radius of an optical cable does not occur and signal transmission quality is ensured.
Description
Technical field
The present invention relates to communication equipment field, more specifically, relate to a kind of optical cable fiber-dividing box.
Background technology
Optical cable fiber-dividing box is the visual plant during fiber optic network is built, and may be used for main cable and the welding of branched cable phase, and is communicated with main cable welding after being integrated by the covered wire cable entering indoor many of user.
Conventional cable fiber-dividing box structure is as license notification number a kind of fiber-dividing box disclosed in the Chinese invention of CN 202472080 U, mainly comprise square casing, be coupled case lid above casing, the one side that casing and case lid face is at the bottom of case, is the sidewall of casing between at the bottom of case lid and case.Be provided with the cable device excessively that confession main cable is passed at the middle part of a sidewall of casing, in casing, press close to this place's side-walls there is the optical cable fixing device corresponding with crossing cable device, for the main cable of passing cable device being fixed.In the middle part of casing, be fixed with fusion splicing devices, it is for by main cable and tail optical fiber welding, and the both sides, front and back of fusion splicing devices distributed the arc-shape winding plate arranged in pairs, for being wound around unnecessary tail optical fiber.Requirement for arc-shape winding plate is the minimum radius bend that the radius of arc-shape winding plate 1 is greater than tail optical fiber.See that (in Fig. 3, dotted line represents optical fiber to Fig. 3, optical fiber is actual has a lot of bundle) easily produced problem be, generally all manually optical fiber 2 is wound on paired arcuate coil plate 1, optical fiber and arc-shape winding plate 1 are difficult to reach laminating closely (meeting is just like the deviation of d displacement in Fig. 3), coiling weak effect, cause the actual crooked process radius of optical fiber to be less than theoretical crooked process radius, have impact on signal transmission effect.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of optical cable fiber-dividing box of SMC material, can fit when ensure that optical cable is wound in wire spool closely, thus ensure that optical fiber does not have too small crooked process radius, ensure that signal transmission quality.
The present invention is achieved through the following technical solutions: a kind of optical cable fiber-dividing box of SMC material, comprise casing, in described casing, arc-shape winding plate is set in pairs, described arc-shape winding plate comprises sleeve and stopper rod, described stopper rod is inserted in described sleeve, and described casing arranges chute, and described arc-shape winding plate slides and is arranged in chute, be positioned at the pickup groove being provided with on rear side of chute and coordinating with described stopper rod at casing, described stopper rod enters pickup groove by sleeve.
In technique scheme, in described sleeve, arrange spring, described spring one end leans stopper rod, and the described spring other end leans sleeve lining.
In technique scheme, the outer wall of described stopper rod arranges draw ring.
The present invention has following beneficial effect: can fit when this invention ensures that optical cable is wound in wire spool closely, thus ensure that optical fiber does not have too small crooked process radius, ensure that signal transmission quality.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of optical fibre winding in background technology.
Fig. 2 is structural representation of the present invention.
Fig. 3 is the cross-sectional schematic that arc-shape winding plate of the present invention coordinates with casing.
Fig. 4 is the structural representation of gripping mechanism of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail: see Fig. 1 to Fig. 4, a kind of optical cable fiber-dividing box of SMC material, comprise casing 2, described tank material adopts SMC material to make, there are excellent electrical insulation capability, mechanical property, thermal stability, chemically-resistant anti-corrosive properties, make casing can reach more than 20 years serviceable life.
In described casing 2, arc-shape winding plate 1 is set in pairs, described arc-shape winding plate 1 comprises sleeve 10 and stopper rod 11, the outer wall of described stopper rod 11 arranges draw ring 13, center of effort is provided when being convenient to pull stopper rod 11, described stopper rod 11 is inserted in sleeve 10, in described sleeve 10, arrange spring 12, described spring 12 one end leans stopper rod 11, and the described spring other end 12 leans sleeve 10 inwall.
Described casing 2 arranges chute 3, and described arc-shape winding plate 1 slides and is arranged in chute 3, and be positioned at casing the pickup groove 20 that on rear side of chute 3, setting coordinates with described stopper rod 11, described stopper rod 11 enters pickup groove 20 by sleeve 10.
When needing coiling, first pull the draw ring 13 on stopper rod 11, pull out stopper rod 11, make stopper rod 11 depart from pickup groove 20, now slide downward sleeve 10, sleeve is reorientated in the pickup groove of downside, then starts coiling, after coiling completes, pull out stopper rod 11, upward sliding sleeve 10, after optical fiber is tightened, unclamp stopper rod 11 make stopper rod 11 enter upside pickup groove in spacing.Therefore ensure that optical fiber and arc-shape winding plate can be fitted closely, coiling is effective, and ensure that and cause the actual crooked process radius of optical fiber can equal theoretical crooked process radius, therefore signal transmission effect is better.
Optical cable gripping mechanism 4 is provided with in described casing 2, described optical cable gripping mechanism 4 comprises guide pin bushing 40, and sliding in described guide pin bushing arranges compressing tablet 41, and described compressing tablet 41 is rotationally connected in a screw rod 42, arrange threaded hole in described guide pin bushing 40 upper surface, described screw rod 42 is twisted and is located in described threaded hole.In described screw rod 42 end, stubborn cap 43 is set.When optical cable penetrates casing, first by described gripping mechanism 4, by turning screw rod 42 downwards, screw rod 42 drives compressing tablet 41 to press down, and is fixed by the optical cable in gripping mechanism 4.
